Anti-aging skincare in your 20s is mostly preventive sunscreen and barrier maintenance. The retinoid-heavy, acid-heavy 'anti-aging' routines marketed to 22-year-olds usually damage the barrier without preventing aging.
What actually prevents premature aging in your 20s
Daily SPF 30+ (highest-leverage anti-aging tool at any age). Antioxidant in morning (vitamin C 10-15%). Gentle cream cleanser. Moisturiser. Avoid: smoking, excessive alcohol, sleep deprivation. That's the whole prevention routine.
What's overkill for most 20-somethings
Daily retinol (overkill until 28-32 for prevention). Acid exfoliation more than once weekly (over-exfoliation territory). Eye creams (your 20-something eyes don't need them). Premium 'anti-aging' serums marketed at your demographic (rarely deliver more than the basic sunscreen + vitamin C combination).
20s skincare is sunscreen + basics + good sleep. The premium anti-aging industry markets to your demographic because it's profitable, not because you need it.
